How is fuel jettisoning typically achieved in aircraft?

Fuel jettisoning in aircraft is typically achieved through a common manifold system that allows fuel to flow from the fuel tanks to designated outlets located in each wing. This method is efficient because it allows for both balanced fuel distribution and controlled release. The use of a common manifold means that all fuel tanks are interconnected, and the system can draw from multiple sources to keep the aircraft stable while jettisoning fuel.

When fuel is jettisoned, the aircraft can manage its weight to meet landing requirements, especially when it has exceeded maximum landing weight due to fuel load. The outlets in each wing assist in ensuring that fuel is dispensed evenly and safely, minimizing the risk of imbalance that could affect the aircraft's performance.

While there are other potential methods for jettisoning fuel, such as gravity flow or automated systems, the use of a common manifold with outlets in each wing is the most efficient and widely adopted implementation in modern aircraft design. This allows pilots to control fuel loss strategically during flight maneuvers.
